Abstract: A projection device includes a first light-emitting component including a first light-emitting member, a first light-transmitting member, a first driving member and a first lens. The first light-emitting member is used for generating a linear light band; the first light-transmitting member is defined with a first linear light-transmitting region; the first driving member is fixedly connected with the first light-emitting member or the first light-transmitting member, and used for allowing the first light-emitting member and the first light-transmitting member to generate a relative motion, and allowing the linear light band to intersect with the first linear light-transmitting region; and the first lens, the first light-emitting member, the first light-transmitting member and the first lens are sequentially arranged. The projection device of the present disclosure is capable of generating the dynamic meteor effect to improve the user experience.

Abstract: A projection device includes a first light-emitting component, a second light-emitting component and a housing. The first light-emitting component and the second light-emitting component are fixed to the housing. A first outer surface of the housing is provided with a first light outlet and a second light outlet; the first light-emitting component is arranged corresponding to the first light outlet; the second light-emitting component is arranged corresponding to the second light outlet; and the first light outlet has a larger area than the second light outlet, such that a projection range of the second light-emitting component is within that of the first light-emitting component. The disclosure can avoid the defect of a single effect of a lamp cap of a projection lamp in the scope of the prior art.
